Error description

  • Error Message: N/A
.
Stack Trace: N/A
.
Performance test is running slower by 1-2%

Local fix

  • 



Problem summary


    

  • Since we enabled the aggressive options in SR4 by default we
removed the aggressive check, but only enabled the optimizations
when 7.0 JCL is used.
This disabled the previous optimizations for 626 JCL with
-Xaggressive.

    



Problem conclusion


    

  • This defect will be fixed in:
6.0.1 SR5
.
Enable aggressive optimizations for 626 if the command line has
-Xaggressive.
